If your Huskee lawn mower blades won't engage, start with the PTO clutch, since that is the most common cause on this type of riding mower. The PTO clutch transfers engine power to the deck through the belt system, and if the clutch is worn out, the solenoid has failed, or the clutch is not getting power, the mower PTO clutch will not work and the blades will not turn. The next likely cause is a bad PTO switch. A defective switch may not send voltage to the clutch, so riding mower blades not engaging can often be traced to a mower PTO switch problem. You can check the switch for continuity with a multimeter, but the PTO clutch itself is not repairable and must be replaced if faulty. On a Huskee riding mower, this symptom is often described as lawn mower blades won't engage or riding mower deck blades will not turn, and both point to the same blade engagement circuit.

01 - Huskee PTO Clutch
The PTO (Power Take Off) clutch provides a means of manually disconnecting the engine from the blades. When the clutch solenoid is energized, the clutch engages the drive belt to drive the rotation of the lawn mower blades. If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.

The PTO switch provides power to the PTO clutch. If the switch is defective, it may not supply power to the PTO clutch. As a result, the clutch won’t engage, and the lawn mower blades won’t rotate. To determine if the switch is defective, use a multimeter to test it for continuity. If the PTO switch is defective, replace it.
